Sump pumping is one of the simplest forms of dewatering and can be very reliable in a variety of different situations. Groundwater is allowed to flow in to the excavation, is collected in sumps and then pumped away.
Overpumping is the process of providing a temporary route to pump water from A to B often by-passing an existing structure such as a manhole or chamber, to ensure a vital continuation of services during construction.
WJ have extensive experience in providing sump pump and overpumping solutions as part of a complete water control strategy for a project.
All WJ pumps are fully tested and serviced before being deployed to site to ensure each pump performs at its optimum efficiency and effectiveness.
